DELIVERY MECHANISM FOR PRINTING- PRESSES.

Application filed October 2, 1925. Serial No. 60,031,

The present invention relates to a new and improved delivery mechanismfor use wlth printing or:cutting and creasing presses or the like, andmore particularly to mechanism especially adapted for the'handling ofheavy stock.

Heretofore,- with machines of this type handling heavy stock such aspasteboard or the like, d'ifiieulties have been experienced at thedelivery end of the machine. The stock rapidly accumulalcs'at thedelivery end and is heavy and cumbersome"tohandle and was .not deliveredto a position convenient for handling by the operator. The speed of themachine was therefore reduced as it was necessary to stop the machine atrelativel short intervals for the removal of stoc worked upon.

Itv is an object of the presentinvention to provide means for thedelivery of worked stock whereby the stock can be readily removedwithout interfering with the operation oi' the,ma'chi ne.

I t' is a further object to provide stock'delivery receiving means fromwhich the stock may be easily removed with the aid of gravity.

It is an additional object to provide a mechanism of this character inwhich the.

delivered sheetsmay be temporarily retained as desired, uponan'intermediate portion of the mechanism.

Itis also an object to provide a mechanism which is relatively simple indesign and adapted for commercial production. and

operation. Other and further objects will appear as the descriptionproceeds. We have illustrated a preferred embodiment of our invention inthe accompanying drawings, in which Figure 1 is a side elevation of aportion a press with our invention attached thereto; Figure 2 is a planView of the delivery mechanism i Figure 3 is a fragmentary view on an enlarged scale showing a portion of the mechanism at the inner end of itsstroke;

The delivery table 11 is supported at one end upon the crossbar 12carried by the brackets 13 secured tothe end of the press frame 14. Thechannel iron 15 rests upon the bar 12 and carries the set screws 16 bymeans of which thetable may be adjusted and held in adjusted position.The outer end of the table is supported by the rods 17, the lower endsof which are pivotally supported at 18 in the end of the press frame.The upper ends of. the rods 17 are adjustably secured to the lugs 19carriedin the brackets 20 located on the lower side of the table 11. Thetable is provided with the adjustable side guides 81..

The outer edge of the table 11 carries the shaft 21 secured thereto bybrackets 22.

This shaft 21 has ke ed thereto the 'stop members 23. Y The sha t isnormally held in position with the stop members at: right angles'to thetable by meansof the coil spring 24. The track members 25 and 25' aresupported from the upper ends of the brackets 13 and 13' by the bolts 26and 26' respectively. The track member 25 carries the cam member 27 tothe lower end of which is pivotally secured the cam rocker 28. The upperportion of the member '27 is provided with the cam surface 29. The

'outer end-of the track member 25 carries the cam member 30 pivotallysecured thereto at 31.- Themember 30 is provided with a flex- ,iblehandle 32, \v hiehn'ormally rests upon The hangers 34 at track members25 and 25 carry the cross rod 7 35, and the hanger 34 on member 25 alsosupports the cam rocker 36 whichjisTpivoted about the point 37. The rod35 carries the stop members 38. The cam rockers 28 and 36 carry the rod39 pivotally supported between them. This rod carries the stopmembers/i= and 41 which are adjustably secured to the rod by. setscrews.

The reciprocated delivery carriage is best shown in Figures 2 and 5, Theside frames 42 and 42 are supported from the blocks 43 and 44 which reston the tracks and 25. Theside frames have the downwardly dependingportions 45 and 46 which extend on the inner sides of the track membersand which support the cross frame members 47 and 48 respectively. Theslats 49 are supported upon these frame members 47 and 48.

he method of connection of the slats 49 is shown in detail in Figure 8,the spring member 50 engaging. the under side of the cross frame memberand yieldinglyholding the slat in place.

The downwardly depending portions 46 of the side frames 42 and 42 havejournaled therein theshaft 51. The knurled roller 52 is carried by theshaft 51 and this shaft also .carries the gearwheel 53. The lower end ofthe ortion 46 of frame 42 is provided with a ug 54 adapted to engage themembers 40 and 41 in the operation of the machine. The side framemembers 42 are rigidly cross connected by the cross frame member 55.They are also cross connected by the rock shaft 56. To the rock shaft 56are fixedly secured the stop finger carriers 57 which carry the stopfingers 58. The roller arms 59 are carried upon the shaft' 56insuchmanner as to rotate freely thereon and they carry at their lowerends rollers 60 which normally rest I upon the knurled roller 52. 4

- The outer end of the shaft 56 has keyed thereto the bell crank lever61 which is provided with the cam rollers 62 and 63 adapted to'cooperatewith the cam surfaces 29 and 30. The cross frame member 48 as shown indetail in Figure 9 carries the brake members 64 adjustably held togetherby .the bolt 65 and wing nut 66. These-brake members en- I gage the endof the knurled roller 52 and prevent overrunning of the roller.

As shown in Figures 5 to 7 the track member 25 has secured to the oposite ends thereof the guide members 6 and 68. These members togetherwith'the track member guide the vertical movement of the rack member.69. This member 69 is provided on its lower surface with the rack 70. iIt is urged downwardly by the springs 71 and 72 housed in bores in theguide members. 67 and .68. The rack member69 is held against downwardmovement by the cam rockers 28 and 36. Y

- The press is provided with mechanism in cluding-b'elts73 and 74 fordelivering the sheets to the reciprocating carnage. Thls mosaicmechanism, however, forms no part of the present invention. The bellcrank lever 75 is connected by the'rod 78 with the reciproeatingcarriage It will be understood that this drive properly co-ordinates themovement of the carriage with the delivery of sheets from the ress.

In the operation of the press, the sheets are delivered from between thebelts 73 and 74 onto the slats 49 of the reciprocating carriage. Theforward edge of the sheet is engaged by hooks 58 and its forwardmovement limited. This forward edge will be gripped between the knurledroll 52 and the rollers 60. The carriage moves downwardly to the rightas seen in Figure 1 underlpower supplied by the rods 78,- This movementis co-ordinated with'the feed of the sheet between the belts-73 and 74.

' i It will be notedthat as the carriage moves downwardly, the rackmember 69 is in the position shown in Figure 6 and the-rack 70 does notmesh with the gear '53. The roller reaches the end of its movement, thecam roller 62 1'idcs up on the surface of the cam 30 which rocks theshaft 56, This rocking movement of the shaft 56 ii ts the stop fingers58 out of engagement ith the'end of the sheet.

Also, at this end of thestroke the lug 54 engages the adjustable stopmember 41 which moves the rod 39 longitudinally and rocks the two camrockers 28 and 36. They are moved to the position in which they areshown in Figure 5. The rack member 69 is forced downwardly by thesprings 71 and 72 and the rack meshes with the gear 51.

The carriage now starts-on its reverse movement back toward the pressand as 1t so moves the knurled roller 1s rotated-1n the clockwisedirection as seen in Figures 1, 3

and 4.- This rotation of the roller feeds the sheet off of the end ofthe reciprocating car-- Kile resting on the receiving vtable 11. The scam surface 29 and rocks the shaft 56. This .52 is held against rotationby thebrake .members 64. As the reciprocating carriage brings the stop 7fingers- 58 down tof their "lower position and into the path of the'next v sheet to be delivered from the press to the carria e. Also, thelug 54 engages the ad-:

and swings thatrod to the, left as seen in Fi res 1, 3 and 4 and totheright as seen in -igures 5 and 6. This movementswings 1 j'ustabTestop member 40 carried by rod 39 the cam rockers'and forces the rackmember 69 upwardly so that the rack 70 clears the gear 53. Rotation ofthe roller is promptly it is desired toremove sheets from the table,

the stop members 23 are swung downwardly as indicated in broken lines inFigure 1 and the. pile of sheets may be easily slid by gravity onto thestripping table 80. As soon as the pile has cleared them the stops 23swing upwardly due to the spring 24.

If it is desired to stop the deposit of sheets on the table 11 duringthis operation this may be accomplished without stopping the press orthe delivery mechanism. In the form of construction shown in Figure 1,the flexible handle 32 is swung outwardly to clear the stop 33 andthenswung downwardly, the cam member 30 rotating about the pivot 31, Thisbrings the cam surface level with the top of the track member 25 and outof the path of the cam roller 62. Consequently, the shaft 56 is notrotated at the end of the stroke and the stop fingers 58 remain in thepath of the sheet. The sheet is, therefore, not delivered from thecarriage during the return movement of the carriage, but is carried backtoward the press. ,The succeeding sheet is delivered on top of thissheet upon the carriage. -When the table 11 is cleared, the cam 30 israised to its operating position and on the next stroke the severalsheets on the carriage are together deposited on the table.

In the form of construction shown in Figure 10, the cam 30 isautomatically swung down out of thepath of the cam roller 62 when thestops 23 are swung downwardly to permit the removal of the sheets fromthe table. This is accomplished by the link 83 which is pivotallyconnected to the bar 84 secured to the cam 30, and the arm 85 which isfixedly secured to the shaft 21 and pivotally'connected to the lower endof the link 83. When the stops 23 are permitted to swing upwardly, thecam 30 is automatically restored to its operative position and thesheets upon the carriage are delivered to the table upon the next returnstroke of the carriage.
